An innovative new system from Tokyo Marui is adapted into this new full metal M4 SOPMOD, including blowback system and also a lock-bolt function which stops the gun from firing on the last round of BB fired (this feature only activated using standard Tokyo Marui 82 round magazine specifically designed for this new M4) just like the real gun and similar to the more expensive Systema PTW. Pop in a new fully loaded magazine, press on the bolt-release button on the side of the receiver and you are ready to fire again!

Employing the new SHOOT & RECOIL Engine Version 2, this new M4 is a blast to shoot with both sound and visual gratification to boot. The gun comes with a standard Tokyo Marui 82 round magazine but it can be set to work in 30rd mode for realism and to force reloads. The gun is of full aluminum (i.e. Full metal) construction with ABS stocks and grips for more realistic feel!

Compact dimensions of 780mm (collapsed stock) to 860mm (extended stock) make the gun very versatile. Uses a 7.2V 1300mah battery stored in the hand guard. Barrel length of 364mm.
